The problem is gone now. I had originally done the chdef -t osimage -p pkgdir before there was a line for rhels7.3-x86_64-netboot-comp_kup. It created a new entry for me with most of the fields blank. There was no rootimg dir, and there had been no pkgdir before I ran the command. Therefore there was nothing to append the new pkgdir to. I went back and cloned an existing line for rhels7.3-x86_64-netboot-comp (with our earlier customizations), then did chdef -t osimage rhles7.3-x86_64-netboot-comp_kup -p kerneldir <...> The result was kerneldir was filled in, and pkgdir was also prepended with the kernel directory. I think this is what was intended in the documented example. I ended up with a bootable image, and the correct kernel/initrd.
Thanks for the help, your solution was much simpler than what I was thinking it would take. -- ddj > On Dec 3, 2018, at 8:57 PM, Yuan Y Bai <by...@cn.ibm.com> wrote: > > Hi David, > > Thanks you pointing out that the doc is not clear about "kerneldir", and make > you confused about "kerneldir" and "pkgdir". > > Here you should use "pkgdir" to append kernels repo directory into pkgdir. > Here is my example, could you try like this, if you have problems, contact me > freely. > > ]# ls /install/kernels/3.10.0-860.el7.x86_64/ > dracut-033-535.el7.x86_64.rpm > dracut-network-033-535.el7.x86_64.rpm > kernel-3.10.0-860.el7.x86_64.rpm > linux-firmware-20180220-62.git6d51311.el7.noarch.rpm > repodata > > ]# chdef -t osimage rhels7.3-x86_64-netboot-compute -p > pkgdir=/install/kernels/3.10.0-860.el7.x86_64 > > ]# lsdef -t osimage rhels7.3-x86_64-netboot-compute -i pkgdir > Object name: rhels7.3-x86_64-netboot-compute > pkgdir=/install/rhels7.3/x86_64,/install/kernels/3.10.0-860.el7.x86_64 > > ]# genimage rhels7.3-x86_64-netboot-compute -k 3.10.0-860.el7.x86_64 > > ]# packimage rhels7.3-x86_64-netboot-compute > > > > > Best Regards > -------------------------------------------------- > Yuan Bai (白媛) > > CSTL HPC System Management Development > Tel:86-10-82451401 > E-mail: by...@cn.ibm.com > Address: IBM ZGC Campus.
